The Panamax M1500 is a Uninterruptible Power Supply (UPS) power conditioner that protects your hifi components from black-outs or brown-outs when the main power is cut out. This will allow you to properly shut down your gears and when the main power comes back on, it will manage the sudden surge of current and keep it stable. Which comes to the other useful features it offer – voltage regulation. By keeping the voltage regulated, sensitive components like CD players, turntables and preamps benefit sonically with a stable supply of voltage in the component. The unit is pretty hefty at around 65lbs with bulk of the weight in the battery packs and the huge transformer. When powered on, you can hear the unit running in a low volume in the background but barely noticeable when 3 or more feet away. 8 Hours is what you would need to fully charge the battery packs. Duration of battery only operation largely depends on what is hooked up to it and their current draw. There are six outlets in the rear so it should pretty much serve the normal needs of most audiophiles unless you have large, current hungry components. Current limit is 1000W.
Cosmetically, the unit is in good shape. A bit of scuff marks here and there but nothing major. We don’t have the original box but will securely pack this for safe shipping. Manual is available online.
